php 调用 mysql 过程未检索结果

Question

我再次来这里寻求帮助，我已经在mysql中创建了一个存储过程，当在像SQLyog或MySQL Workbench这样的sgb上调用它时，我正常检索查询结果，但是当我这样做时在 php 上执行同样的操作并执行 mysql_query，没有给出任何内容。

这是我执行 mysql 查询的函数。

function conect($SERVER){
        if (strtoupper($SERVER) =='MYSQL') {
        $this->con=mysql_connect(SQL_SERVER,SQL_USER,SQL_PASSWD)or die(mysql_error());
        $this->db=mysql_select_db(SQL_DB,$this->con);
            if ($this->con == 0){
                $retorno = "CONECTION ERROR - SERVER!<br>";
            }
            else if ($this->db == 0){
                $retorno = "CONECTION ERROR  - DATA BASE!<br>";
            } else {
                $retorno = "";
            }

            return  $retorno;

        }

    }

    function isConected(){
        if($this->con == false)
            return false;
        return true;
    }

    function execute($qry, $res="load"){
        if(!$this->isConected())
            $this->conect('MYSQL');

        $this->result[$res] = mysql_query($qry, $this->con) or trigger_error(mysql_error() . ": \n" . __FILE__ . ": \n" . $res . " - " . $qry);
        if($this->result[$res])return true;
        trigger_error(mysql_error());
        return false;
    }

    function get_fetch_assoc($res="load"){
        return mysql_fetch_assoc($this->result[$res]);
    }

这是我的过程调用

$mysql = new conexao();

            $qry = "CALL spGetChamadoMaisAntigo('".$uareas."', '".$_SESSION["dpto_codigoUrl"]."')";

            $mysql->execute($qry, 'Load');

            while($row = $mysql->get_fetch_assoc('Load')){
                $chamadosAbilitados[] = $row;
            }

我已经测试了这个函数，使用

进行了一个简单的查询

select * from tableName

并且正常返回结果。

这是我的程序

DELIMITER $$

DROP PROCEDURE IF EXISTS `ocomon_rc6`.`spGetChamadoMaisAntigo`$$

    DROP TABLE IF EXISTS ocomon_rc6.TempChamados;
    END$$

DELIMITER ;

有人知道我做错了什么吗？

解决了，这个教程我已经分析过http://www.joeyrivera.com/2009/using-mysql-stored-procedures-with-php-mysqlmysqlipdo/它给了我一个答案，需要声明它需要发送到php的所有参数，并将选择的结果插入到这个参数中，我修改了我的程序，并使用@调用带有此输出参数的程序，最后做了一个使用 @ 简单选择此输出参数，如下所示。

更改了程序的参数

DROP PROCEDURE IF EXISTS `ocomon_rc6`.`spGetChamadoMaisAntigo`$$

CREATE DEFINER=`renancr`@`%` PROCEDURE `spGetChamadoMaisAntigo`(IN Sistema VARCHAR(1000),IN CodigoUrl INT, OUT numero INT, OUT diasAposAbertura INT)

更改了内部选择并将其插入到输出参数中

SELECT idOcorrencia, dias_apos_abertura INTO numero , diasAposAbertura FROM TempChamados WHERE dias_apos_abertura = (SELECT MAX(dias_apos_abertura) FROM TempChamados);

在 php 中，我更改了程序的调用，如下所示。

$qry = "CALL spGetChamadoMaisAntigo('".$uareas."', '".$_SESSION["dpto_codigoUrl"]."', @numero , @diasAposAbertura)";
$mysql->execute($qry, 'Load');

最后我选择了如下输出参数。

$qry = "SELECT @numero , @diasAposAbertura";
$mysql->execute($qry, 'Load');
